ClickDefender vs ClickLens

ClickDefender is a paid click-fraud protection service for PPC campaigns on Google Ads and Microsoft Ads. It uses a JavaScript tracking script, real-time detection, analytics, IP blocklists, API access, and alerts. The maker says its AI evaluates clicks across more than 50 signals, including browser fingerprints, scroll depth, time on page, click patterns, and other behavioral indicators, to identify bots, click farms, and competitor activity. Dashboards report traffic sources, IP addresses, geographic distribution, device types, and fraud trends. Google Ads can receive blocked-IP exclusions every six hours, up to 500 IPs per campaign. Microsoft Ads automation is listed as in development; users can export a blocklist for manual import. Slack alerts and HTTP webhooks send fraud events externally. Setup supports JavaScript or Google Tag Manager, with guidance for WordPress, Shopify, Wix, Squarespace, and custom HTML. Plans start at £49 a month, with a seven-day trial requiring a payment method and converting to a subscription unless canceled.

ClickLens scores advertising sessions for click fraud and grades conversion provenance in real time. Its JavaScript tag evaluates each session against more than 40 behavioral signals, including device fingerprint consistency, automation markers, and network indicators. Scores range from 0 to 100: above 70 is classified as human, 40 to 70 as suspect, and below 40 as bot. Conversion verdicts can pass, downweight, or retract a conversion, and the dashboard identifies the signals and flags behind each verdict. Installation guides cover Shopify, WordPress, WooCommerce, and Google Tag Manager. Google Ads IP and placement exclusions can sync automatically. Microsoft and Meta placement sync is rolling out, while TikTok placements are report-only. The tag does not collect names, email addresses, phone numbers, form values, or typed text. It is about 13 KB gzipped, loads asynchronously, and does not block page rendering. The Free plan covers 1,000 sessions per month; Starter costs $49 a month and covers 10,000 sessions per month. After a monthly session limit is reached, the tag keeps loading but stops sending data until the account is upgraded.
